You clearly read none of my original post that you replied to before spouting off speculation about why you think the mini would not be viable, while failing to address the large screen Plus models that everyone should supposedly want to buy, but was unceremoniously discontinued after the two iPhone release cycles, just like the mini; as well as the Air and its reportedly poor sales that will seemingly lead to its discontinuation after this year's release.This is so unrealistic and delusional. If you put all of those pro features and screen in to a phone that tiny you’ll get about 3 hours of battery life…. The battery you are able to fit in there is pretty small, specially if you’re adding more lenses, etc….. And even if Apple were to somehow pull this off and offer a decent battery life, people still wouldn’t buy it….. the hard truth is that the majority of folks already got used to bigger screens… and the handful of tiny phone enthusiasts on tech forums aren’t going to move the needle. When are we going to finally put this to rest…. It won’t sell, and Apple is not bringing it back.
Now, to dispense with the facts. The ProMotion display is actually more power efficient than a display running at a full 60 Hz the entire time because the display can ramp down to 1 Hz when idle.
The ultrawide lens uses as much space as the telephoto. It's a one-for-one swap, no change in the battery size or capacity is involved.
The Pro mini model that I described would have better power efficiency before even factoring in efficiency advancements that all iPhones have gotten with newer A-series SoCs, newer basebands (both, newer Qualcomm, and further efficiencies likely to come with the Apple C2 this year), and any battery technology and firmware-level battery management improvements that were not backported to the 13 mini.
The 13 mini had good enough battery life for millions of buyers to purchase it and enjoy it, anyway. A 17 Pro mini or 18 Pro mini would only be better in every regard, as I outlined above, so there's no reason to suggest that it's "unrealistic" or "delusional" that, among three other monster-sized phones that get released every year, Apple would and should consider offering a single model that fits the needs of millions of people who don't want a literal half pound (8 oz/233g) 7" brick in their pocket.
I don't understand how anyone does not find the Pro Max size and weight objectionably difficult to carry or use one-handed, but to each their own. For some reason, even though the critics got what they wanted and the mini was discontinued three models ago, there's apparently this primitive attraction to every discussion about the mini solely to criticize anyone and everyone who appreciated having or wanting a modern smartphone with that size and weight.
